Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Brake Fluid Level

Locate the brake fluid reservoir (usually near the driver's side).
Remove the cap and check the fluid level.
- If low: Top up with the correct type of brake fluid (DOT 3 or DOT 4).
- If fluid is fine: Proceed to the next step.

3. Inspect the Emergency Brake System

Physically inspect the emergency brake lever for proper operation.
Ensure the cable is not damaged or frayed.
Check the brake pads and rotors for excessive wear.

4. Replace Brake Fluid (if necessary)

If the brake fluid was low, bleed the brake system to remove air.
- Tools Required: Brake bleeder kit, wrench.
- Procedure:
  1. Attach the bleeder kit to the brake bleeder valve on the caliper.
  2. Open the valve and allow fluid to flow until clear of bubbles.
  3. Close the valve and check fluid levels, repeating for each brake.

5. Replace Brake Switch (if faulty)

If continuity tests failed on the brake switch:
- Tools Required: Socket set, new brake switch.
- Procedure:
  1. Disconnect the electrical connector from the brake switch.
  2. Remove the old switch using a socket.
  3. Install the new switch and reconnect the electrical connector.
